Definitely get the Ar7's. Without a doubt, just from your description of the kind of skiing you do the Ar7's are for you. At your weight I would consider looking at the Thall if you want a softer ski though. I'm 6' 2", 155lbs and I have a pair of Thalls. Love them to death, very soft, can butter the shit out of them. Just a heads up the Ar7's are stiff at least compared to the afterbangs and Thalls. But with the dimensions of the Ar7's your pretty well covered for an all mountain ski that excels in the park.
